question on transaction replication

Hello,

I am using SQL Sevrer 2012 Standard Edition. I am using Transactional replication with publication, distribution and subscription all on one server which is server Y. Tables a,d,c,d,e,f  are being replicated from database1 to database2. now I want to bring another server Server X and setup transaction replication between Server X and Server Y and replicate tables a,b,c from database 3 on Server X to tables a,b,c on Server Y and still let the other replication run on Server Y between the same tables.

So for tables a,b,c on Server Y they are kind of subscribed tables for database1 from database 3 on server X at the same time publisher for database2 on server Y.

Is this possible?
